本研究首先利用4-疊氮苯胺及硝基苯胺對單壁奈米碳管做化學修飾與共價改質，最後使用葡萄糖及氫氧化鉀加熱產生氫氣環境下對產物進行還原。化學修飾是利用UV點光源以光化學反應的方式產生活性大的自由基，使4-疊氮苯胺與奈米碳管管壁反應，得到管壁苯胺官能基化的奈米碳管，並藉由表面的官能基與硝基苯胺做後續氧化聚合反應。還原的目的是為了使共價改質後奈米碳管上的NO2拉電子官能基轉換為NH2推電子官能基，期許經由此項製程方式實現現今發展較瓶頸的N摻雜奈米碳管。由傅立葉轉換紅外光光譜分析、高解析電子能譜分析及熱重分析可以證實我們在單壁奈米碳管上有效合成及還原硝基苯胺聚合物。透過掃描式電子顯微鏡影像及拉曼光譜分析表面形貌及D/G比值，可以確認奈米碳管化學改質後結構的完整性。由拉曼光譜分析、電性分析、霍爾分析及功函數可以證實化學改質後奈米碳管的N摻雜效應。且經過一個月的觀察，化學改質奈米碳管在有機溶液或去離子水中穩定分散，其薄膜導電率均在誤差範圍內，表明我們成功製備穩定的N摻雜奈米碳管，在碳材料領域是一項重大的突破。

In this study, 4-Azidoaniline and Nitroaniline were used to chemically modify and covalently modify SWNTs. The products were reduced under the hydrogen atmosphere by heating with glucose and potassium hydroxide. Chemical modification is the use of UV light source photochemical reaction to generate large active free radicals, so that 4-Azidoaniline and SWCNTs reaction to obtain functionalized SWCNTs. By the surface of the functional groups and Nitroaniline do the subsequent oxidative polymerization grafting. The purpose of the reduction is to make the pull electron-free radical NO2 on the covalently modified SWNTs into push electron-free radical NH2. By FTIR, XPS and TGA, we can confirm the efficient synthesis and reduction of nitroaniline polymer on SWCNTs. The surface morphology and D/G ratio were analyzed by SEM and Raman spectroscopy to confirm the structural integrity of the carbon nanotubes after chemical modification. Raman spectroscopy, electric analysis, Hall analysis and work function can confirm the N-doping effect of the carbon nanotubes after chemical modification. After one month of observation, the chemically modified carbon nanotubes were stably dispersed in organic solvent or deionized water, and the film conductivity is within the error range, indicating that we successfully prepared stable n-doped carbon nanotubes. It is a major breakthrough in the field of carbon materials.
